ANTICBEEPER.

Be 1t known that .I, PHILIP W. Moons, residing at Evanston, iIr-the county of Cook and State of Illinois, have invented a certain new and useful Improven'ient 1n Anticreepers, of;

which the following is a full, clear, concise, and'exact description.

My invention relates to improvements in anti-creepers or rail anchors, and more par ticularlyto that type of device wherein a rivet, pin or bolt is carried by the anti-- creeper and passes through an opening in the web of the rail as an aid in securing the anti-creeper in position. In such de flange has been located on that side of the center line of the rail base adjacent to the portion provided with the in or rivet. The creeping thrust of the rail under these conditions tends to skew the anti-creeper and force it from its proper position on the rail developing stresses which tend to tear off the rivet.

Theobject of the present invention is to rovide an anti-creeper of this general type 111 which this difficulty is overcome.

In illustrating the invention, I have each of which the tie-abutting flange is located near the opposite side of the rail base; that is, the side of the anchor away from the side that carries the rivet.

parts, the skewing action is the tendency to tear oil the rivet is considerably lessened. Other ad vantages are also obtained, as will. be apparent from the following description:

Figure Lof the drawings is a top'plaii viewof one form of anti-creeper, the rail being broken away in part.

Fig. 2 is a. sideelevation thereof.

Fig. 3 is a rear elevation thereof, the rail reversed, and

Fig. 4 is a top plan view of a second forin'oif anti-creeper shown applied to the rail Fig. .5 is a side elevation thereof; and Fig. 6 is a rear elevation thereof with the rail shown in section.

I The first form of rail anchor consists or' abase member 1 extending beneath the rail base from one side to the other and rhaving integral jaws 2, 3 at the sides of the rail base, each of which is arranged to fit The jaw 3 is pro- VVith this ar- I Specification of Letters Patent. t t d 13, 1911 Application filed June 16, 1916. SeriaI No. 103,971.

vided with a vertical extension 4 adjacent to the web 01 the rail and carries a suitable fastening device, such as a pin, rivet or bolt 5, which passes through an opening in the web of tl e rail (3. The rail is supported on the usua (truss. lie 7 against which a downwardly extending flange 8 bears. Said flange is loca .ed at the left of the base member as shown in Fig. 3, whereas the vertical extension 1 and the pin 5 are connected with the right hand side thereof through the jaw 3. In other NOi'liH, the .pin supporting element and th: flange are connected to opposite sides of the base plate.

When the rail creeps, the anchor tends to skew in suc ,1 a direction that the jaws 2 and 3 increase their grip on the rail base.

There is ver .7 little tendency to tear out the rivet in view of the fact that said skewing is resisted primarily by said jaws and the base plate i1 stead of being resisted almost wholly by ihe vertical extension 4.

The rail anchor maybe made as a casting of suitable metal, such as malleable iron for example, or it may be stamped from a steel plate and brnt to shape, or 1t may be other wise formed In applying it to the rail base, it is turned at such an angle as to provide the maximu in possible distance between the jaws 2 and I5, which it is'swung to the position shown in Fig. l, and the rivet 5 passed thro Jgh the opening in the web of the rail. .Ihe opening in the web may be drilled by rsing the opening in the rail anchor as a tamplet. The type of fastening means shown inl igs. 1 to 3 is a rivet which has prefers cly a driving fit in the opening in the rail, although other fastening means may obviously be employed. Furthermore, the opening in the rail need not necessarily be in the vertical web thereof, but may be otherv. se iocated. The fastening device prever s Sli ewing of the rail in a direction to decrease the effectiveness of the grip of which is illustrated as a bolt '13, but which rivet, or other suitable equiva may be a p in,

lent means for securing said extension to the web of the rail. A tie-abutting fiange 14 is arranged at one side of the central axis of the rail as in the previous construction.

In applying the rail. anchor to the rail base, the jaw 11 is applied to one side there of and the extension 12 is then bent over the opposite side of the rail base as far as pos' sible by hammer blows, thus forming a second jaw. The creeping tendency of the rail tends to skew the anchor, but the skewing is resisted by the jaws on opposite sides Whereby'there is little tendency to tear out the rivet.

This form of rail anchor may be conveniently stamped from steel, although it may. also be made as a malleable casting or of other suitable material.

The invention is not to be limited to the embodiments thereof described, various other forms may be devised which fall Within the scope of the appended. claims.

Having thus described my invention,

what I claim as new and desire to secure by Letters Patent of the United States is:

1. An anti-creeper comprising a member beneath the rail base, an integral aw there on-fitting one side of the rail base and canrying a locking pin, and a tie abutting ex tension on said member located toward the other side of said rail base to cause said anchor to skew.

2. An anti-creeper comprising a member beneath the rail base, an integral jaw there on fitting one side of the rail base and carrying alocking pin, a tie abutting extension on said member located toward the other side of said rail base to cause said anchor to skew, and a second jaw on said member on the slde adjacent to said tie-abutting flange said jaws increasing their grip on the raii base when said anchorskews. I

3. .An anti-creeper comprising a member which. extends beneath the rail base from one side to the other, a jaw at each end thereof, a downwardly extending projection on said member near one of said jaws, the

other of said jaws having an opening and means passing through said opening and through an alined opening in the rail to aid ber, means at opposite sides thereof engaging the sides of the rail base, anextension on one of said means arranged adjacent to the vertical Web of the rail, fastening means cooperating With said extension and said web to secure the anchor to the rail, and a tieabutting flange on said base member'on the side thereof opposite said-extension.

In witness whereof, l hereunto subscribe my name this 9th day of June A. D., 1916.
